Lead or support process design activities including basis-of-design development, process calculations, mass balances, process flow diagrams, P&IDs, equipment sizing and selection, specifications, control narratives, and system layouts.
Evaluate and integrate treatment technologies such as biological treatment, membrane systems, reverse osmosis, activated carbon, advanced oxidation, and other physical/chemical treatment processes.
Address challenging constituents including PFAS, metals, ammonia, organics, dissolved solids, and other conventional and emerging contaminants.
Work closely with equipment vendors and technology providers to evaluate, select, and integrate packaged and vendor-supplied treatment systems.
Collaborate with multidisciplinary engineering teams responsible for civil/site, mechanical, structural, electrical, instrumentation, controls, PLC/SCADA, storage, containment, and supporting infrastructure.
Provide technical leadership during equipment procurement, construction, commissioning, startup, troubleshooting, and system optimization.
Develop strong relationships with landfill owners, operators, solid waste companies, technology providers, and other industry partners.
Support proposals, client development, and strategic pursuits as McKim & Creed continues expanding its presence in the solid waste market.
Mentor engineers and help strengthen the technical capabilities of our growing treatment team.
